Having described the'principal parts involved in our invention we will now briefly. describe the operation of the same.

The cams C and C revolve in the direction of the arrow thereby releasing the levers B and allowing them to rise and also allowing the mold frame contained between the plates B and B to rise in the guide ways The mold frame and molds are then carried upwardly by means of the i counter weights A until the screw flanges loo L and L are in contact with the bottom of the molds formed b the slidable members D and D. In his position of the screw the major portion or body L projects through the opening formed by the at their inner ends and so that the openings formed by the notches D are concentric with the center'of the molds D. Simultaneously the spill board G is tiltedinto a horizontal position substantially.on a level with the bottom of the notches D of the molds D by means of the counter weights G During ,this operation the buckets I and I of the conveyer I carry cement from the hopper H upwardly so as to deposit it in the main portion J of the hopper J which leads the cement to the chutes J The chutes J deliver an :equal portion of the cement into each mold D. 'Itwill be understood that the former heads L are rotated continuously being driven through the main shaft by the s rockets K and K sprocket chain K sha t K bevelgears K and L and vertical shaft L It will be readily seen that as the former revolves within the'mold that the screw flanges contained in the mold will gradually force the cement downwardly beneath the flanges until the cement is packed to the required. density. By this means the tile is gradually built up within the mold and as it is built up the mold itself is gradually forced downwardly away from the flanges by the cement packed between the flanges and the bottom of the mold and against the pressure of the counter weights A which tend to hold the mold and the packed cement against the flanges in forming the tile may be varied by taking L and L. Of course as the molds D are forced downwardly the counter weights A are gradually raised; The pressure required off one or more supplemental weights from the weight A. This operation continues until the flanges L and L and the former headare .on a level with the bottom of the notches D of the mold D. Through these notches the surplus cement left in the mold at this stage of the operation isthrown radially outwardly by the revolving wings L onto the horizontally set spill board G.

The former head L continues to revolve I with the flanges L and L in contact with the upper end of the tile thereby finishing off such upper end smoothly and evenly. By the time this operation is completed the cams C and C have revolved sufiiciently to bring the rollers B again into engagement with the eccentric portions of the cams thereby forcing the levers B downwardly and carrying the mold frame and molds 1) the connecting links B and into the position shown in the drawings that is, onto the upper surface of the platform M Immediately the mold has reached the level of the platform M the plate N secured to the face of the cam' C in a similar manner to the cam G engages the roller D throwing the lever D on its fulcrum E and thereby carrying the arm D thereof against the arm 13 and raising the arm B and thereby throwing the forked ends B of the bell cranks B and B outwardly. This operation carries the slidable members D and D outwardly from beneath the bottom of the molds D. The molds are now in a position for opening. This operation is accomplished by means of the plate N of a cam C engaging the roller F and forcing the rear end of the lever F downwardly and the forward end of the lever F upwardly against the arm F The forked arm F as has been before described is directly integral with the arm F and moves in unison therewith. As the arm F is forced upwardly the forked arm F also carries the plate D upwardly in the guide ways D. This movement moves the pins D and D from the top of the slots 13 and B to the bottom of the slots ID and B or into the position shown in the drawings. By this operation the levers D and D are carried around on their fulcrum formed by the pins 13 and B. This operation carries the levers D and D around their fulcrums by reason of the sliding of the pins D and D in the slots B and B and by means of the pins 1) and D, D and D which are fastened to the fiattened end of the rods D and D, D and D andengage the levers D and D in forked ends D and D and in the slots D and D thereby movin the rods D and D longitudinally in t e direction of the arrow and the rods D and D longitudinally in the opposite direction to that indicated by the arrow Fig. 5. As has been before described the arms D, D, D and D" are secured on the rods D D, D and D and will therefore when operated separate the sides 2 and 3 ofv the molds D at the central split D To insure of the tile passing freely from the mold, the 'opening mechanism is arranged so-that the top end of the mold is opened first thereby freeing the major portion of the tile and yet supporting it in the mold around the bottom. It

will be noticed that the slot B is formed with the vertical portionB. It will thus be seen that as the plate D is carried upwardly as hereinbefore described that the slot B will operate the rods 1) and D by the initial movement of the mechanism so as to open the upper end of the mold. Durare operated to open the bottom of the mold thereby depositing the tile on the platform M The mold frame and mold D again rise as herein before described carrying the 'mold free of the tile. .As the mold frame and mold D is brought to this lowermost position the arm G engages the right angular portion G thereby tilting the spill board from a'horizontal position into a position shown and depositing the spilt cement onto the supplemental spill board G5. Asthe mold frame again rises the spill board G is so balanced to drop again into its normal or horizontal position.

The supplemental spill board G is tilted rearwardly by the counter Weights G thereby depositing the surplus cement on the bucket-portion H of the chain conveyer H The conveyer slots I-I convey the surplus cement back again into the supply hopper H. After the tile has been made and de posited on the platform M as hereinbefore' described it is necessary to move the truck M forward suiiiciently to allow of deposit? ing another set of tiles on the platform. This is accomplished by the following means. The roller N journaled on the cam C engages with the cam plate N" swinging the lever N forward. The lower forked end of the lever N straddling pin N car-- ries the bar N longitudinally forward tilting the bell cranks M on their pivot M 'and freeing the brake shoe M from the periphery of the wheel M thereby freeing the wheel and allowing the truck to be pushed forward by'the bar N and spring dog N. As soon as the roller comes into contact with the arm N the reverse movement is imparted to the bar N thereby freeing the ratchet bar M and allowing the bell crank M" to swing again into the normal position and carry the brake shoe into contact with the wheel M thereby positively locking the truck in position and ready to receive another set of tiles.

In order to vary the feed of the truck in proportion to the size of the tile we have provided the adjusting bolt N which passes through the slot N into the arm N thereby allowing of the adjustment of the arm N so as to vary the throw of the arm N The platform M provided with the legs M rests upon the lower rectangular frame M so as to be removable. When the platform M has received its full complement oftiles, such lat-form may be removed with its supporting legs from the frame M and placed away for storage and another platform placed in position upon the frame M.

Although in this specificationwe"refer to our machine 'as a cement tile making machine, it will, of. course, be understood that the machine may be used for many purposes such as making drain pipes and sewer p1 es.
